AI Analysis

Impact

In the addr_remap_address_map function of remap.c, a logic error permits a local attacker to gain System execution privileges without any user interaction. The flaw bypasses required privilege checks during address remapping, allowing the attacker to elevate authority to the highest system level on the device. This flaw is classified as CWE-693.

Affected Systems

Android operating systems on Google devices are affected. The advisory does not specify exact kernel versions, so any device running a vulnerable Android build should verify its kernel image and apply available security updates.

Risk and Exploitability

The EPSS score is < 1%, indicating a very low but non-zero exploitation probability. The CVSS score of 6.7 indicates moderate severity. The vulnerability is not listed in the CISA KEV catalog, and the flaw can provide a local attacker System execution privileges without user interaction. Exploitation does not require any special user action, so an attacker with physical or local remote access could potentially trigger the flaw. The lack of publicly known exploits implies the threat is likely low to medium.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Install the latest Android kernel that contains the patch.
  • Enable SELinux enforcing mode to enforce the updated policy.
  • If the device cannot receive an update, restrict address‑remapping by configuring operations or disabling the related kernel module.
  • Monitor system logs for any signs of unexpected privilege escalation.
